What are the aesthetics in this plot?
What geometric object is being plotted?
Univariate (One Variable) Visualizations – For Numerical Data
Is this aesthetic global or local?
binwidthBivariate (Two Variables) Visualizations – For Numerical Data
Scatterplots
Faceted Histograms
Side-by-Side Boxplots
Stacked Density Plots (Ridge Plots)
Multivariate Plots
There are two main methods for adding a third (or fourth) variable into a data visualization:
Colors
Facets
Measures of Center
Not Resistant
Mean
Resistant
Median
Measures of Spread
Not Resistant
Variance
Range
Resistant
Inner Quartile Range (IQR)
Given this distribution…
What measure of center would you use? Why?
Parameter: True value of the statistic for the population of interest
Point Estimate: provides our best guess for the value of the parameter
Estimates based on larger samples tend to be more accurate than those based on smaller samples.
